  • Patent number: 10319480
    Abstract: A weakly ionized plasma of ions and neutrals is generated from a first reactant in a confinement region. Orthogonal electric and magnetic fields induce azimuthal rotation of the ions around a longitudinal axis of the confinement region, the azimuthal rotation of the ions imparting azimuthal rotation to the neutrals of the first reactant, and promoting repeated collisions between one or both of the ions and the neutrals with a second reactant. The repeated collisions produce an interaction between the neutrals and the second reactant that produces a product having a nuclear mass that is different from a nuclear mass of any of the nuclei of the neutrals and the second reactant.

  • Patent number: 10319486
    Abstract: Isotope enrichment by laser activation wherein a multi-isotopic element Q, like Uranium, Silicon, Carbon is incorporated into gaseous QFn, QF6, QF4, QOmFn, etc and diluted in gas G like He, N2, Ar, Xe, SF6 or other inert gas; and wherein that mixture is cooled by adiabatic expansion or other means encouraging formation of dimers QF6:G in a supersonic super-cooled free jet; and wherein that jet is exposed to laser photons at wavelengths that selectively excite predetermined molecules iQF6 to iQF6*, thereby inducing rapid VT conversions and dissociations of iQF6*:G?iQF6+G+kT, while leaving non-excited dimers jQF6:G intact; and wherein a skimmer separates the supersonic free-jet core stream containing heavier jQF6:G dimers from lighter core-escaped iQF6-enriched rim gases.

  • Patent number: 10311987
    Abstract: An autonomous facility for storing spent nuclear fuel includes a building forming an enclosed interior space containing a water-filled spent fuel pool. The pool includes fuel racks containing spent fuel assemblies which heat the water via radioactive decay. A passive cooling system includes a submerged heat exchanger in the pool and an air cooled heat exchanger located in ambient air outside the building at a higher elevation than the pool heat exchanger. A heat transfer working fluid circulates in a closed flow loop between the heat exchangers via unpumped natural gravity driven flow to cool the fuel pool. The air cooled heat exchanger may be enclosed in a concrete reinforced silo adjoining the building for impact protection. The building may include a cask pit formed integrally with the pool to allow fuel assembles to be removed from a transport cask and loaded into the fuel rack underwater.

  • Patent number: 10304573
    Abstract: A method and a corresponding device for the pressure relief of a nuclear power plant having an outlet for a relief flow. The relief flow is guided out of a containment into the atmosphere via a relief line provided with a filter system. The filter system has a filter chamber with a filter-chamber inlet and outlet and a sorbent filter arranged therebetween. The relief flow is guided in a high-pressure section of the relief line past the filter chamber, with the latter being heated, and the relief flow is expanded at the end of the high-pressure section and dried. In order for efficient retention of iodine-containing organic compounds, the relief flow is guided through a bed filter, guided in a superheating section past the high-pressure section of the relief line and in the process is heated, guided in this state directly thereafter through the filter chamber having the sorbent filter.

In some cases, one or more alignment pins also extend between two sections of a fuel wedge to align the sections. In some cases, one or more seals are also disposed between two sections of a fuel wedge. Thus, in some cases, the reactor core can be relatively long (e.g., to be a pipeline reactor). Other implementations are also described.
